Lung Cancer

Locally advanced non-small cell lung cancers share a risk of both local and systemic recurrence and justifies a therapeutic strategy combining focal and systemic treatment. In resectable stage IIIA-N2 tumors, peri-operative chemotherapy significantly increases survival rates. Chemoradiotherapy, which is the standard treatment of non-resectable locally advanced tumors, may have a role as an induction treatment to reduce locoregional recurrence rates.In the present phase II trial, we aimed at comparing standard induction chemotherapy (arm A: cisplatin and gemcitabine) with 2 different regimens of induction chemoradiotherapy (total dose: 46. Gy) including third-generation cytotoxic agents (arm B: cisplatin and vinorelbine; arm C: carboplatin and paclitaxel) in patients with resectable stage IIIA-N2 NSCLC, using feasibility of the whole strategy, including surgery, as a primary endpoint.A total of 46 patients were included. Response rate was significantly higher after induction chemoradiotherapy vs. chemotherapy (87% vs. 57%, p=0.049). A total of 44 patients underwent operation. The feasibility rate of the proposed therapeutic strategy was 89% for the whole cohort, 93% in arm A (induction chemotherapy with cisplatin and gemcitabine), 88% in arm B (induction chemoradiotherapy with cisplatin and vinorelbine), and 87% in arm C (induction chemoradiotherapy with carboplatin and paclitaxel) (p=0.857). Overall median, 1-year, and 3-year survival were 30 months, 87%, and 43%, respectively.Induction chemoradiotherapy with modern treatment regimens is highly feasible and may show promises in the current and future developments of multimodal therapeutic strategies in locally advanced NSCLC. © 2009 Elsevier Ireland Ltd.
